4 Claims. lA

The invention relates to a sorting table pad for automatic spoolers of the type employed for winding yarn from spinning bobbins to larger packages, known as cheesesj for the purpose of combining a number of relatively short threads into a single long strand of yarn. In the operation of automatic spoolers of the Barber-Colman type, the empty bobbins and bobbins with yarn on that have broken down during running are ejected from their holders to a conveyor which deposits them on a sorting table lat one end of the machine where the operator sorts out those having yarn thereon and puts them-back in the bobbin holders to be tied again. The empty bobbins are dropped into trucks beneath the table, while those with badly tangled yarn or with too small an amount of yarn to be economically handled on the spooler, are sent to a smaller winding machine known as a tailings machine.

As the sorting tables provided on Barber-Colman spoolers are made of steel, the operators have followed the practice of placing linoleum, fiber board, cardboard, leather or artificial leather sheets onto the surface of the sorting table to protect the wooden bobbinsagainst damage as they are ejected onto the table from the conveyor. It has been found that these sheets usually wear out rapidly at the point where the bobbins contact same intheir fall from the conveyor. It has also been found that the bobbins tend to pile up on the sorting table between sorting operations, thereby causing bobbins being ejected to strike against bobbins in the accumulated pile, thus causing bobbin damage.v

The present invention contemplates the provision` of a pad adapted to be mounted upon the upper surface of a sorting table, the pad being preferably formed of rubber or rubber-bonded fibers to receive the wooden bobbins as they are ejected from the spoolei` conveyor.

This invention further contemplates the provision of a pad formed of resilient material and provided with a resilient rubber bumper which acts to disperse the wooden bobbins over the entire surface of the sorting table to prevent the formation of an accumulated pile.

This invention further contemplates the provision of a sorting table pad embodying a resilient base pad, -a bounce pad, adapted to be adjustably positioned along the base pad and a bumper mounted on the bounce pad, the three members being secured in adjusted position by means of bolts extending upwardly through the base pad and bounce pad for threaded engagement in nuts embedded within the bumper.

This invention further contemplates the provision of a sorting-table pad which is relatively simple and inexpensive to manufacture, which may readily be adjusted for use, and which will have a relatively long service life.

This invention embodies` other novel features, details of construction and arrangement of parts which are hereinafterset forth in the specification and claims and illustrated in the accompanying drawing wherein: v

Fig. 1 is a top plan view showing a pair of sorting table pads embodying features of this inven tion mounted upon a sorting table of the type employed with a Barber-Colman spooler.

Fig. 3 is a side elevational view illustrating a sorting table pad.

Fig. 4 isa top plan view of same.

Fig. 5 is a sectional view taken along the' line 5-5 of Fig. 3.

Fig. 6 is a fragmentary top plan view illustrating a modified form of this invention.

Fig. 8 is a sectional view, corresponding to Fig. 7, illustrating another modified form of this invention. l Y 'i y' Fig. 9 is an end elevational view illustrating another modied form of this invention.

Referring now to the drawing for a better understanding of this invention, the sorting table pad 6 is adapted to be mounted upon the upper surface of a sorting table l. The sortingtable illustrated in the drawingis of Ia type employed with Barber-Colman spoolers and provided with two adjoining surfaces 8 and 9 which slope outwardly and downwardly fromv an apex l0 to re l vceive wooden bobbing 4 falling by gravity from the discharge end of an endless conveyor which is shown in dottedroutline at 5 in Fig. l.

Referring nowgmore particularly `tolii'gs. 1 to 5, inclusive, in the'drawings, the pad 6 is shown as comprising a base pad Il which is'preferably'cut from a sheet of rubber or rubber-bonded fibers and of sufcient width and laength to substantial,- ly cover one of the inclined surfaces 8 or 9 of the sorting table. A bouncev pad l2, preferably formed of resilient rubber, is provided on the upper surface of the base pad Il and preferably disposed adjacent the apex IB of the sorting table. A bumper pad I4 is provided on the upper surface of the bounce pad l2 and is preferably formed of relatively soft resilient rubber to readily absorb the shock of bobbins falling thereon from the conveyor 5.

The base pad Il is shown formed with a pair
